Toxic Chemical

May 19, 1985

QUEBEC — All humans and animals in Quebec have been exposed to polychlorinated biphenyls, according to a report by the Quebec Environment Department. PCBs are used as a coolant in transformers and in paper recycling mills, aluminum smelters, paint and chemical factories, petrochemical plants, electrical equipment manufacturers, aerospace factories, foundries and food processing plants. The toxic chemical has been proved to be a cause of cancer in laboratory animals and birth defects and kidney and liver ailments in humans.
